You must read it! High Court in London identified errors in al Gore's movie http://scienceandpublicpolicy.org/monckton/goreerrors.html A small extract: Error 8 ''Polar bear dying'': Gore says a scientific study shows that polar bears are being killed swimming long distances to find ice that has melted away because of global warming. They are not. The study, by Monnett & Gleason (2005), mentioned just four dead bears. They had died in an exceptional storm, with high winds and waves in the Beaufort Sea. The amount of sea ice in the Beaufort Sea has grown over the past 30 years. A report for the World Wide Fund for Nature shows that polar bears, which are warm-blooded, have grown in numbers where temperature has increased, and have become fewer where temperature has fallen. Polar bears evolved from brown bears 200,000 years ago, and survived the last interglacial period, when global temperature was 5 degrees Celsius warmer than the present and there was probably no Arctic ice-cap at all. The real threat to polar bears is not global warming but hunting. In 1940, there were just 5,000 polar bears worldwide. Now that hunting is controlled, there are 25,000. Error 21 ''Peruvian glaciers dissapearing'': Gore says that a Peruvian glacier is less extensive now than it was in the 1940s, implying that global warming is the cause. It is not. Except for the very highest peaks, the normal state of the Peruvian cordilleras has been ice-free throughout most of the past 10,000 years. Error 23 ''Sahara desert drying'': There is no drought caused by “global warming. In 2007 there were record rains across the whole of the southern Sahara. In the past 25 years the Sahara has shrunk by some 300,000 square kilometers because of additional rainfall. Some scientists think global warming may actually mitigate pre-existing droughts because there will be more water vapor in the atmosphere.
